MathDoku

About this game

Based on the same rules as the hit KenKen(tm) game, as printed in the New York Times and The Times (uk).

Related to Sudoko, but with a mathematical twist - use the arithmetic challenges in each cage to help solve the puzzle.

Ratings and reviews

I love this game and have been playing it for quite some time now. I like the feature that you can hide operators and make it more difficult. My only issue is that I updated it a week ago, and the puzzle board got smaller and the copy button disappeared. The copy button was quite helpful for pasting "maybe" numbers easily. I can still live without it, but I don't know why the puzzle screen got smaller. Anyway to make it bigger as before? Hard to play 9*9 puzzles even on big screen phones.

I've had this app over 5 years and across multiple phones. No bugs, never crashes, no ads. Good variety of difficulties and game options, and all the features/buttons work well. EDIT: 2022, still love this app, still just as good, over 300hrs of games logged. Would recommend to anyone who loves math/logic/puzzle games.

I've been playing Mathdoku (also known as Kenken - a name protected by copyright) for years, through a series of phones and tablets, and on paper as well. This is a great, crash-free, ad-free app, with enty of variations. More complex than Sudoku, with a whole range of math and logic strategies to figure out and employ. As easy - or as difficult - as you choose!
